I enjoyed the art style, it had a lot of polish between the rotating sky in the background the little particle effects for the player moving, the lengthy animation of you falling into the hole setting in that you failed (grr lol), and the things to jump on. I liked the music as well, it was nice to listen to whilst playing. The menu screen was a bit confusing in my opinion, I tried clicking on them and realized that I had to use my arrow keys to select the options. I found it hard to use the character, even with the double jump, I would have actually preferred a little bit floatier jump (would have felt better and fit better for your space theme). It was hard to jump between the platforms even with the abundance of things there to help you get over because they would sink too much to get any leverage or the rocket moved too fast without parenting your character as a child for when you jumped on; you would just slide right on off. I found my self getting stuck on the bottom right satellite and that was frustrating. If the mechanic was that you were in space and everything was being sucked into the black hole and you had to jump between them as the objects came down bouncing between them getting sucked into the black hole rather than just trying to keep your oxygen up. I am just trying to be critical, I am sorry if I came off as harsh. I really did enjoy your art style but the execution felt off; I hope you keep making games because I like your style - Keep it up!
